ath6kl: Fix memory leak of rx packets in endpoint 0
htc_packet and htc_packet->buf_start are separately allocated for endpoint 0. This is different for other endpoints where packets are allocated as skb where htc_packet is skb->head and they are freed properly. Free htc_packet and htc_packet->buf_start separatly for endpoint 0.
